Fall is definitely my favourite season of the year. For me, it’s a combination of a bunch of things:

The weather: who doesn’t love those crisp evenings where you can go for a walk with your bud?

The clothes: scarves, tights, knitted sweaters, flannel, tall boots, cute hats, say no more!

The food: cinnamon, nutmeg, pumpkin, squash, soups, low-n-slow recipes, comfort food. My oven is put to the test this time of year. No complaints from me!

The colours: the burnt orange and red colours of the maple leaves are so pretty.

The smells: food and otherwise, like those fall candles. On sale, I recently picked up a bunch of pumpkin-scented ones and they are amazing.

Growing up in rural Newfoundland, another scent that resonates strong with me (and brings back wonderful memories) is the smell of wood burning fireplaces, especially on a cool evening. That smell just takes me right back; something about it.

And, of course, hubby and I were married during fall, so it holds a special place in my heart. So, yeah, fall is my jam!

Ingredients for a roasted butternut squash and sweet potato soup recipe.

How To Make Butternut Squash Sweet Potato Soup

I’m usually always making some kind of soup, even in the summer, but especially in fall and winter. Typically, I make soup on Sunday and it’s such a regular occurrence that now Sunday in our home is unofficially “Soup Sunday.”

This easy butternut squash soup is always a favourite. It’s unbelievably creamy and super flavourful. Full details are in the recipe card below, but here are the basics:

Roasting the butternut squash takes the longest, so get that going first while you prepare the rest of the butternut squash and sweet potato soup.
Meanwhile, cook the aromatics (onion and garlic). Stir in sweet potato and seasonings.
Add some broth and cooked squash and bring to a simmer until sweet potato is cooked through.
Off the heat, stir in Greek yogurt and maple syrup (for a little sweetness).
Use an immersion blender to blend that soup up.

How To Roast Butternut Squash

Butternut squash is pretty easy to prepare. Again, full details are in the recipe card below, but here are the basics:

Carefully cut butternut squash in half. Scoop out seeds with a spoon.
Drizzle butternut squash with a little oil and sprinkle with salt and pepper.
Place squash cut sound down onto a parchment paper-lined baking sheet.
Bake squash on 400 degrees Fahrenheit for about 40 minutes or until it’s tender when pierced with a knife.
Let cool slightly and then scoop out flesh to use in this recipe. Easy!

How to Garnish This Soup

With this crisp, cool weather it’s the perfect time to be making and eating a nice big bowl of this warming butternut squash and sweet potato soup. The finishing touch? Crispy sage leaves.

Our garden is overflowing with sage. It’s not one of those herbs we use a lot, but when crisped, it’s magical. I wouldn’t recommend eating raw sage, though. It doesn’t taste great; to me it tastes like pine.

Cooked up in a pan with a little oil and then sprinkled with salt? Yum! I could eat them like potato chips! This fried sage leaves recipe is the one I use.

Other delicious garnish ideas for soup are:

Swirl in an extra dab of Greek yogurt or cream over top
Some roasted squash seeds (top just before serving or they’ll get soggy)
Buttery croutons
Drizzle of olive oil
Crumbled goat cheese
